Cyano and dinos?

[Dylan McKenzie Holloway]

Hello all, recently let my phosphates and nitrates bottom out after to many water changes and under feeding. I think I caused a cyano and dinos bloom in my tank. Just trying to confirm my suspicious with other people. I unfortunately do not have a microscope.

This stuff seems to grow all over, some areas form bubbles as well so that's why I'm thinking Dino's. The purple blows off pretty well and comes back in a day or so, but the brown/green fuzz doesn't blow off. Haven't really had any stringyness though like with dinos.

Also could this cause my corals to be upset/die? Ever since this showed up my coral has not been doing good. Not sure what to think of that.

looks like dinos is a possibility. they dont always produce bubbles and they can be toxic to corals.

See if you can round up a microscope, even a cheap toystore one can work to ID dinos

Could be both.

It seems you have at least two different types of algae: 1) brown/green fuzz; 2) brown strands. I can't really see the brown/green fuzz so I am ignoring this.

The brown strands could be several things. Look at taricha: tests for diatoms, cyano, and dinos.

@mcarroll I am linking a thread I started that noticed my ORP was super low and I thought that was probably due to dinos. Anyone else notice the same thing? https://www.reef2reef.com/threads/can-dinos-cause-really-low-orp.325625/#post-4035164 I'll continue updating there.

I recently took a picture of dinos in my tank. If you can get a magnifying glass close to the strands you might distinguish the little buggers.

let them fight together and once one win, medicate him.
